Abstract
Objective: The aim of this report is to present the clinical results of using free chimeric iliac osteocutaneous flaps based on the periosteal branch of the superficial circumflex iliac artery (SCIA) in complex metacarpal reconstructions.
Methods: Reconstruction using free chimeric iliac osteocutaneous flaps was performed in a series of seven patients who underwent metacarpal reconstruction for complex metacarpal defects between March 2009 and March 2012. The procedure was performed for bone and soft tissue losses associated with posttraumatic infections (four patients) and posttraumatic bone and soft tissue defects (three patients).
Results: The skin paddles of the chimeric flaps had a median size of 3 × 7 cm, and the iliac segments had a mean size of 1 × 1 × 3 cm. The median follow-up time was 18 months. All the flaps survived completely with no signs of infection. Osseous union occurred within a mean period of 3 months, and the range of motion achieved for the metacarpal phalangeal joints was 0–80°. The patients were satisfied with the aesthetic outcome.
Conclusions: Chimeric iliac osteocutaneous flaps may be a useful alternative for treating complex metacarpal defects because they yield a thinner skin paddle and less bulky bone segment than traditional flaps.
